Abstract: 15,980. Dey, J., and Dey, A. Aug. 4. T i m e - checking apparatus for workmen. A special form of casing, c a r d positioning and gripping means, and a device for printing in different colours records taken at different periods are described. The front portion of the casing is formed by a detachable cover 2, Fig. 1, the top of which is held behind a door 5. This door can be fastened to a second door 6 at the side, by a lock 7 and also by a hook 8. The cover carries two card-gripping jaws on a slide which can be shifted horizontally, a pin being linked to this slide and adapted to engage one of a series of holes in the cover. An indicator may be placed on the casing to show the positions of the card which correspond with these holes. The card-holder 10 proper is carried by two uprights, and can be slid off when the cover has been removed. One of the gripping-jaws is fixed to the slide, while the other can be moved slightly and is pulled away from the first by a spring to leave room for the insertion of a card. The movable jaw is pushed by a cam on the slide against the inserted card to grip it before printing takes place. This cam has a downwardlyprojecting pin, which is shifted by an extension 38 of a rocking frame 29 which carries a platen 32. This working frame is actuated manually through a bar 34. The record-card is positioned vertically by means of a ledge 80, Figs. 1 and 3, in the holder 10, connected to a rack 84 which is raised automatically or manually by a form of pawl 85. This pawl is journaled in a yoke at the end of a rocking shaft 87, which has an arm pressed upwards by a spring ; the arm is depressed by a pivoted clock-driven cam 92 of the form shown in Fig. 3, but only when the cam is rotated in the direction indicated. This vertical positioning device is similar to that described in Specification No. 15,977, A.D. 1905. In order, however, to prevent the rack from being raised more than one step at a time, the yoke before-mentioned carries another pawl 108 engaging a rack 107 facing the reverse way to the former, to which it is attached. When the racks have reached their highest point, a pin on the first presses a releasing-piece 99 into the path of the actuating-pawl, against a spring, the releasing-piece being mounted on the frame as by screws and slots. The releasing-piece is raised by the next movement of the actuating-pawl 85, this pawl being pressed by it away from the rack. The releasing-piece is shaped so that it then presses away a holding-pawl 95 and allows the racks to fall. It is then pushed back by its spring, so that the racks can be raised afresh. The yoke of the rock-shaft carries a pin 109 enabling it to be rocked manually by a rod 111 carried by a vertical sleeve and projecting through the casing. The rod can be detached if automatic action only is desired. Printing is effected from a multi-colour ribbon by improved apparatus of the type described in Specification No. 6200, A.D. 1905. The ribbon 43, Fig. 1, is carried by spools which can be shifted laterally by a connecting-bar 46. This bar is connected by a slotted link 47 to a pin on one end of a horizontal pivoted lever 49, the other end of which carries a wedge 52, Fig. 1 and 4. This wedge can be pushed to one side or the other, and the ribbon shifted accordingly, by a second wedge 53 which is depressed by hand against a spring 55. The pin-and-slot connexion between the shifting-bar 46 and the lever 49 allows the latter to be moved slightly so as to bring the lower wedge 52 on the opposite side of the operating- wedge 53 without shifting the ribbon. This slight motion is effected automatically by a bell-crank lever 66, one end of which is spring-pressed against a cam-disk 64 having a series of notches and rotated every twenty-four hours by the clock-work of the time-printing wheels. After the end of this bell-crank lever has entered a notch, the next depression of the cperating-wedge will shift the ribbon. To render this setting operation quite sharp, the cam-disk carries a series of studs 72 which are in the path of a rocking lever which stops the disk just before the bell-crank lever 66 is ready to enter a notch. The cam-disk is driven through a spring connexion, so that, when the disk is released, it is at once snapped forward and setting promptly effected. Release of the disk takes place when the rocking lever is raised by a lug on the minute-printing wheel.
